ALL-STEEL TRUCK.

, Specification of Letters Patent.

Patented June 15, 1915.

Application filedMarch 27, 1911. Serial No. 617,202.

To all whom it may concern Be it known that I, ARTHUR'OLSTEBBINS,

Lansing, Michigan, have invented certain new and useful Improvements in All-Steel Trucks, of which the following is a specification.

This invention relates to improvements in hand trucks.

The main objects of this invention are, first, to provide an improved hand truck formed mainly of metal, which is comparatively light in weight and at the same time is very strong, rigid and durable; second, to provide in a metal hand truck improved 7 legs; third, to provide in a metal hand truck an improved arrangement of parts, whereby the wheel brackets and the axle serve the additional purpose of a brace.

Further objects, and objects relating to structural details, will definitely appear from the detaileddescription to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of my improved hand truck. Fig. II is an enlarged detail inverted perspective view showing the leg structure and the arrangement of the cross pieces, side bars and handle. Fig. III is a detail vertical section on a line corresponding to line 33 of Fig. I. Fig. IV is an enlarged detail section taken on a line corresponding to line 44 of Fig. III.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the angle iron barsl are arranged with their angles facing inwardly. These side bars are formed of heavy sheet metal. The vertical members of the side bars are considerably wider than their horizontal members, as greater stress comes upon the bars in this direction than sidewise. As an additional strengthening means for the side members of the side bars, I provide them with longitudinal corrugations 2. The side members are connected by cross pieces 3, 4, 4 and 5, the front cross piece 3 being an angle iron piece arranged with its angle facing rearwardly.

The other cross pieces are formed of channel iron, being formed up of heavy sheet or plate metal, the same as the side bars. The ends of the cross pieces are arranged in the angles of the side bars, the ends of the top members of the cross pieces 4, 4 and 5, belng bent downwardly between their side members to form the attaching members 6, which are secured to the side members of the side bars, as by the bolts 7. The intermediate cross pieces 4, 4 are provided with stiffening strips 8 of wood which are secured in the channels by means of the bolts 9, arranged therethrough and through horizontal members of the side bars. The rear cross piece 5 is secured to the horizontal members of the side bars by means of the bolts 10 as shown.

The nose 11 is provided with arms 12 and 13, the strap like arms 13 being extended over and secured tothe cross pieces by bolts 14. The arms 12 are arranged on the horizontal members of the side bars.

The wheel brackets 15 are arranged in the angles of the side bars, the forward ends of the brackets being arranged in the angle of the front cross piece 3, the parts being secured by bolts 16, arranged through the arms 12, the brackets and the interposed horizontal members of the side bars and front cross piece. The wheel brackets are also secured to the side members of the side bars by means of the bolt 17. The axle 18 extends between the brackets. The wheels 18 are revolubly mounted on the axle. This arrangement of parts secures a bracing and reinforcing at a point where heavy strains are received.

The legs 19 are U-shaped and formed of angle iron arranged with the angles facing inwardly. The upper ends of the legs are arranged in the angles of the side bars and they are secured to the vertical members of the side bars by means of the bolts 20 and 21. The inwardly projecting members of these angle iron legs are folded forwardly at 92, to permit the arranging of the handles 23 in the angles of the side bars, as illustrated. The handles are notched at 24 to receive the legs. By forming the legs as shown at 22, the notches 24 to receive the legs do not materially weaken the handles. The handles are secured by the bolts 25 arranged through the horizontal members of the side bars. Thus secured the handles can be readily replaced when required without may be broken. The legs are braced by the braces 26,.the lower ends of the braces being arranged in the angles at the lower ends of the legs and secured to the vertical members thereof by the rivets 27. The upper ends of the braces are arranged in the channel of the rear cross piece 5 and secured thereto by means of'the bolts 14:- These braces thus arranged, not only serve to brace and support the legs but serve the additional purpose of reinforcing this rear cross bar so that a reinforcing or stiffening strip 8 is not required. I have shown and described the parts as being largely connected by bolts. It will be understood that rivets may be used if preferred. By forming and arranging the parts as I have illustrated and described they are disposed so as to secure 7 full advantage of the strength of the material, with the result that comparatively light material may be used. This is, as will be obvious, a decided advantage, sirable to provide a strong, rigid, durable Copies of this patent may be obtained for as it is de i truckjatthe same time it should be as light as possible. Having thus described my invention,

what I claim as new and desire to secure by- Letters Patent is: p

In a hand truck, the combinationof angle iron side bars arranged with their anglesfacing inwardly,cross pieces connecting said side bars, U-shaped angleiron leg members arranged with their angles facing inwardly and with their upper ends in the angles of said side bars and secured to the vertical members thereof, the upper ends of the in wardl-y projecting flanges of the rear arms of the said U-shaped leg members being folded forwardly, leg braces arranged with their lower ends in the angles of the lower ends of the leg members'and secured to'the vertical flanges thereof, the upper ends of the braces being secured to one of the cross pieces, and handles arranged in the angles of said side bars securedto the horizontal members thereof, said handles being notched to receive the portions of said leg members having the folded flanges; I

In witnesses whereof,

I have hereunto set my hand and seal in the presence of twoy.
